Purify multichannel amplifiers manufacturers

[pogo]

If you comply with the IPC, I don't see any problems there.

Outside the ridiculous "benchmark" statement
- internal build quality is meh due to awful soldering/routing of the speaker outs
- interesting integration of 8 Purifi 1ET400A layouts on a single board, better done than T&A
- min impedance 4 Ohm non bridged. Really?

I inquired with Lyngdorf about which modules they use. Here is there response: "We don't utilize any Purifi modules. We have implemented the Purifi Eigentakt technology on our own 4-layer PCB and specified the components."

I wish that their design would allow for 800w bridged into 4ohm speakers as that would make for a good solution. Absent bridging, bi-amping six channels for LCR would be the only way to get that power, but I am not confident that would benefit my setup. Possibly better to wait for the 1ET9040BAs...

This is technically right, they took the 1ET400A layout and pasted it on their own layout 8 times.

That's a spicy meatball!

Could you explain what you think T&A got wrong? Or point out the thread where this was discussed, as I couldn't find it.

Nothing wrong, just a bit quick and dirty. They didn't even remove the footprint for the connector.

The same PCB area looks like this on Lyngdorf

The reference layout has mostly been retained here, which is not necessarily a bad thing.

The reference layout HAS to be retained. Removing an unused connector footprint is not really altering a layout.

T+A is one of the leaders in amplifier construction and hf is a b*tch. Probably, they didn't leave it in the layout for no reason. I'll try to ask them.
